Pc guru idea is ok.
I think you can also chip this in.
Print a random number from the php getdate function.
Then you can also get random letters if you like from Abc now concatenate the random number with the letters this will give you a unique number. This is why i said so note that the Php getdate function gets the numeric value of the a day, month, year, time, minutes, and seconds, and join it as one and no day,month,time join together can repeat itself so when this generate the random number add some little random alphabets or you can multipl some little number to it and this gives you what you want.
